Best External Battery Pack: Having Power When You Need it

Our busy lives in this modern world of technological innovation mean that charging portable devices in transit become a necessity. We tend to use a lot of devices – for music, video, photography, navigation, camp reading, etc. – but they won’t be functioning without a power supply. This is where the best external battery pack becomes the smart solution for on-the-go charging and recharging, especially when you are in the middle of nowhere.

Outdoor enthusiasts and travelers will find these battery packs useful for their device-charging needs. Imagine going out to scenic landscapes aiming to capture the precious moments or work on your laptop at the beach, but then realize your power has been depleted. This inconvenience can be prevented by having a reliable and powerful external battery pack.

There are many battery packs available in stores near you. How to choose the best one? This article has the details you’ll need, including an overview of what an external battery pack is, how it works, and its significance. We will go through different external packs to provide you full insight into the important aspects. But let’s first go through a tabular comparison of these products and then delve into things to consider before buying these external packs.

Things to Consider Before Buying

Every buyer’s decision must be preceded by a careful understanding of the perks the product delivers. So, before making your decision on which external battery pack to buy, it is imperative to know more about this device.

Let’s go through some of the important considerations hereunder that you need to handpick the best battery pack among others. Take note of the significant difference of the specifications for each pack. Some details you should know about battery packs include:

Input

It is well and good to have an external battery pack to charge your devices, but the question is how long does it take to fully charge? Some devices may require six hours or less to charge to their full capacity, while some may even take as long as 12 hours.

Combined Output

Most battery packs are equipped with a minimum of two USB ports, which are oftentimes labeled as 1A or 2.1A. These ports can handle as much as 1 amp or 2.1 amps. The only difficulty to overcome is the maximum output of the ports the pack can deal with.

Its maximum output can reach 3 amps, allowing you to have the full capability of both ports when you use them all at once. This will make your charging time faster. However, keep in mind that not all battery packs come with the ability to cope with each simultaneously-used USB port.

Durability

If you are a traveler, adventurer or an outdoor enthusiast, you would probably want to bring a battery pack with you for your mobile devices. The housing material of the battery can have a huge impact on its aesthetics and longevity.

Its metal housing ensures the survivability of your device from normal wear and tear for years. The internal components of the battery should be kept away from heat.

Portability

The large size and weight of a mobile phone battery does not do you any good, especially when you are camping or mountaineering. Always consider the volume, weight, and shape of your external battery packs.

Built-in Extra

An indicator becomes relevant so you will never wonder how much power is left in your external battery. There are battery packs using LED indicators showing the percentage of the remaining charge.

Be mindful of the fact that the best LED indicators are developed with over four LEDs for accurate representation of the charge left. Yes, extras tend to be silly, but can be very useful in certain situations.

Henry was hiking since he was 4. He was lucky enough to be born in Boulder, Colorado and enjoy Rocky Mountain National Park hikes growing up. His favourite is Longs Peak, which rises to 14,259 feet (4,346 m) above sea level. It is the highest point of the park. Henry likes to explore new hikes and spend his spare time in the wilderness.

Nothing puts a damper on your adventure like having no battery for your phone to capture the memories. My worst camping trip was last year when we reached the campsite and realised we had forgotten to carry an external battery to charge our phones. Now the Crave Travel Pro 13000mAh Dual USB Ultra-High Density Power Bank gets packed before anything else. It’s light to carry and we can both charge our phones at least twice.

Henry Silva

That’s quite an adventure, I can see that! No phone working? Tough! I can see why the Crave Travel Pro gets priority inside your backpack, and for good reasons. Its fast charging time makes it a crowd-pleaser, and it’s very affordable, too!

Matt Gibson

When it comes to portable chargers, I swear by the Intocircuit 26000mAh High Capacity Power Castle Portable Charger External Battery Pack mainly for its amazingly big capacity. If I am just charging my phone, I can go about twelve full rounds or I can charge my iPad 3 fully and still remain with enough juice to charge my phone more than once. It comes in a sleek style and with a nice little pouch.

Henry Silva

At 26000mAh, it does pack a punch and the material is also sturdy. The stylish and streamlined look is a bonus for those who want their gadgets looking great while doing its job! Thanks for dropping by Matt!
